【摘要】 遥感影像在应用之前必须经过一些预处理,图像融合是预处理的一个重要环节。本文以QuickBird全色和多光谱影像为基础,通过应用遥感图像处理软件ERDAS8.7版四种不同的融合方法进行融合实验,并结合主、客观方法来评价四种融合方法的融合结果,从而得出基于QuickBird影像的森林资源调查中较可取的遥感影像融合方法——小波融合法和主成分分析法。更多还原

【Abstract】 Some pretreatment is necessary before the application of remote sensing images,while image fusion is an important part of the pretreatment.This article introduces the application of fusion technology of remote sensing image in the investigation of forest resources,which based on the QuickBird panchromatic and multi-spectral image,by using four different methods of software ERDAS8.7 version,combined with subjective and objective methods to evaluate the fusion results,then obtained that wavelet fusion method and principal component analysis are desirable image fusion method of the four different ones for large-scale survey of forest resources based on QuickBird image.更多还原
